bool "Enable low power mode"
help
Enable this to put the device in low power mode between measurements.
By default the device will always be on. Enabling this also adds a delay
based on "Conversion time" to each measurement call for bringing the
device out of standby.
config TMP00X_USE_RAW_VALUES
bool "Enable raw ADC readings"
help
Enable this to return raw ADC readings. By default measurements are
converted to Celsius.
